According to the ideal gas law (PV = nRT), when the volume (V) and temperature (T) are the same for both gases, the pressure (P) is directly proportional to the number of moles (n) of gas. Since 1 mole of hydrogen is produced while only 0.5 moles of oxygen are produced, the pressure of the hydrogen gas will be twice that of the oxygen gas, meaning the pressures are not equal.
Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. 1 mole of hydrogen gas and 0.5 moles of oxygen gas are produced from 1 mole of liquid water and are collected into separate containers of the same volume at the same temperature. Are the pressures of the gases equal? in one to two sentences, use the ideal gas law to explain your answer.
